G.W. Leibniz
modernRationalism1646 – 1716
Gottfried Wilhelm Leibniz (1646–1716) was a German polymath and rationalist philosopher whose work spanned mathematics, metaphysics, logic, and theology. He independently developed calculus alongside Newton and constructed an elaborate metaphysical system centered on monads, pre-established harmony, and the principle of sufficient reason. His Theodicy remains a landmark attempt to reconcile divine perfection with the existence of evil in what he famously called 'the best of all possible worlds.'
